Version 6.6 19 Mediant 2000

User's Manual 1. Overview

1 Overview

This manual provides you with the information for installing, configuring, and operating the

Mediant 2000 SIP gateway (referred to throughout this manual as device).

The device is a SIP-based Voice-over-IP (VoIP) media gateway. The device enables voice,

fax, and data traffic to be sent over the same IP network.

The device provides excellent voice quality and optimized packet voice streaming over IP

networks. The device uses the award-winning, field-proven VoIPerfect™ voice

compression technology.

The device incorporates 1, 2, 4, 8 or 16 E1, T1, or J1 spans for direct connection to the

Public Switched Telephone Network (PSTN) / Private Branch Exchange (PBX) through

digital telephony trunks. The device also provides SIP trunking capabilities for Enterprises

operating with multiple Internet Telephony Service Providers (ITSP) for VoIP services. The

device includes two 10/100Base-TX Ethernet ports, providing redundancy connection to

the network.

The device supports up to 480 simultaneous VoIP or Fax over IP (FoIP) calls, supporting

various Integrated Services Digital Network (ISDN) Primary Rate Interface (PRI) protocols

such as EuroISDN, North American NI2, Lucent™ 4/5ESS, Nortel™ DMS-100 and others.

In addition, it supports different variants of Channel Associated Signaling (CAS) protocols

for E1 and T1 spans, including MFC R2, E&M immediate start, E&M delay dial/start, loop

start and ground start.

The device, best suited for large and medium-sized VoIP applications is a compact device,

comprising a 19-inch, 1U chassis with optional dual AC or single DC power supplies. The

deployment architecture can include several devices in branch or departmental offices,

connected to local PBXs. Call routing is performed by the devices using internal routing or

SIP Proxy(s).

The device enables users to make cost-effective, long distance or international

telephone/fax calls between distributed company offices, using their existing

telephones/fax. These calls can be routed over the existing network using state-of-the-art

compression techniques, ensuring that voice traffic uses minimum bandwidth.

The device can also route calls over the network using SIP signaling protocol, enabling the

deployment of Voice over Packet solutions in environments where access is enabled to

PSTN subscribers by using a trunking device. This provides the ability to transmit voice

and telephony signals between a packet network and a TDM network.

Notes:

• The device is offered as a 1-module (up to 240 channels or 8 trunk spans) or 2-

module (for 480 channels or 16 trunk spans only) platform. The latter configuration

supports two TrunkPack modules, each having its own IP address. Configuration

instructions in this document relate to the device as a 1-module platform and must

be repeated for the second module as well.

• For channel capacity, refer to the device's specifications in 'Selected Technical

Specifications' on page 697.

User's Manual 20 Document #: LTRT-68822

Mediant 2000

The figure below illustrates a typical device applications VoIP network:

1.1 SIP Overview

Session Initiation Protocol (SIP) is an application-layer control (signaling) protocol used on

the gateway for creating, modifying, and terminating sessions with one or more

participants. These sessions can include Internet telephone calls, media announcements,

and conferences.

SIP invitations are used to create sessions and carry session descriptions that enable

participants to agree on a set of compatible media types. SIP uses elements called Proxy

servers to help route requests to the user's current location, authenticate and authorize

users for services, implement provider call-routing policies and provide features to users.

SIP also provides a registration function that enables users to upload their current locations

for use by Proxy servers. SIP implemented in the gateway, complies with the Internet

Engineering Task Force (IETF) RFC 3261 (refer to http://www.ietf.org).
